I recently just updated to the newest version of java as is recommended but as soon as I did that I lost all my files for my server as I am the host therefore I have the files. My start.bat file went as well as all the ban files and server permissions, properties etc. I remade the start.bat file but it has made a new world and everything has been undone. Any way I can restore the old files as I spent a long time making this server. Thanks for any help.
